SY/T5037 Kauv Steel Pipe

 

SY/T5037 tus qauv qhia qhov ntev, zoo, zoo, kev ua tau zoo, kev xeem, kev soj ntsuam cov cai, txheej, cim, thiab daim ntawv pov thawj zoo rau submerged arc welded steel kav rau kev thauj mus los ntawm cov kua dej zoo tib yam (nrog rau cov seam ncaj thiab kauv seam submerged arc welded steel kav. , hereinafter hu ua "steel pipes"). SY/T5037 kauv welded kav yog tsim rau thauj cov kua dej xws li dej, cua, thiab cua sov chav.

Lub nominal sab nraud txoj kab uas hla ntau rau SY/T5037 steel kav yog tsis muaj tsawg tshaj li 219.1 hli, thiab lub nominal phab ntsa thickness ntau yog t Ntau tshaj los yog sib npaug zos rau 3.2 hli. Lub nominal sab nraud txoj kab uas hla thiab phab ntsa tuab ntawm cov kav hlau yuav tsum ua raws li cov kev cai ntawm SY/T6475. Yog tias koj xav tau lwm yam kev qhia tshwj xeeb ntawm SY / T5037 steel kav, GNEE Group tuaj yeem muab cov kav hlau txuas ntawm lwm cov kab thiab phab ntsa tuab.

Kev tshuaj xyuas ntawm SY/T5037 Steel Pipes

• Tshuaj muaj pes tsawg leeg

1. Cov qauv tshuaj ntsuam xyuas tuaj yeem raug coj los ntawm cov kav hlau ua tiav lossis steel strips / daim hlau. Thaum sampling los ntawm steel strips / phaj, cov qauv qauv yuav tsum ua raws li cov qauv kev cai ntawm steel sawb / phaj txheem. Thaum kuaj los ntawm cov kav dej steel, qhov chaw kuaj yuav tsum tsis pub tsawg tshaj 1/4 ntawm qhov kev ncua deb ntawm cov welds uas nyob ib sab, los yog kwv yees li 90 degree los ntawm txoj kab ncaj nraim.
2. Kev tshuaj xyuas tshuaj muaj pes tsawg leeg yuav tsum tau ua raws li qhov cuam tshuam ntawm GB / T4336 lossis GB / 223. Nyob rau hauv rooj plaub ntawm kev tsis sib haum xeeb, cov txiaj ntsig ntawm kev tshuaj ntsuam ntub dej yuav tsum yeej.

• Tensile Test

1. Cov qauv ntsuas tensile rau cov pob qij txha welded yuav tsum tau coj mus rau qhov txuas ntawm qhov txuas. Lub vuam yuav tsum nyob rau hauv nruab nrab ntawm cov qauv, thiab yuav tsum tau raws li qhov yuav tsum tau ntawm daim duab 3, nrog rau cov weld reinforcement tshem tawm. Nws raug tso cai kom flatten tus qauv ntawm chav tsev kub.
2. Tsuas yog raws li tau teev tseg hauv tus qauv no, kev ntsuas tensile yuav tsum tau ua raws li GB / T2651, nrog rau qhov ntsuas kub ntawm 23 degree ± 5 degree (los yog chav tsev kub).

• Impact Test

Kev ntsuam xyuas cuam tshuam yuav tsum tau ua raws li GB / T229.

• Guided Khoov Test

Cov kev taw qhia khoov yuav tsum tau ua raws li GB / T2653.

• Hydrostatic Test

Kev ntsuas hydrostatic yuav tsum tau ua raws li GB / T241.

• Acid Etching Inspection ntawm Welded Joints

1. Acid etching tshuaj xyuas ntawm pob txha pob txha ntawm cov kauv thiab ncaj welded pob qij txha yuav tsum tau nqa tawm sai li sai tau tom qab lub weld tiav.
2. Acid etching kuaj yuav tsum tau muab los ntawm cov yeeb nkab kawg siv txoj kev txiav roj. Cov kua qaub etching nto yuav tsum yog hauv av kom cov kab fusion tuaj yeem pom meej tom qab etching. Cov qauv yuav tsum tsis txhob hammered los yog deformed ua ntej qhov kev xeem.

• Kev kuaj tsis muaj kev puas tsuaj

1. X-ray tshuaj xyuas
Txoj kev tshuaj xyuas yuav tsum ua raws li Daim Ntawv Ntxiv A lossis lwm cov qauv sib npaug rau Daim Ntawv Ntxiv A.
2. Kev kuaj Ultrasonic
2.1. Kev kuaj ultrasonic ntawm welds yuav tsum ua raws li SY/T6423.2.
2.2. Kev kuaj ultrasonic ntawm 25 hli dav ntawm cov yeeb nkab kawg yuav tsum ua raws li SY/T6423.4.
